I think It's not easy. Gold is the most efficient asset in the world and people want gold everytime in the history. Because gold is meaning glory and wealth. Bitcoin or any other cryptocurrency not. 
Yes that is true, bitcoin is surely more stronger than gold and right now bitcoin is the king and i think gold has no chance on bitcoin because in the future bitcoin is we will more great and i know the value of it is we will surely pump more high and in that way gold has no chance to beat bitcoin.
